Background technique

In the fifth generation mobile communication technology (5th-Generation, 5G) and Long Term Evolution (LTE) systems, the air interface capabilities of terminals such as User Equipment (UE) are controlled through radio resource control (Radio Resource Control, Reported by the RRC) layer. In the face of more and more frequency band combinations, differences in the capabilities of each combined frequency band, Multiple-Input Multiple-Output (MIMO) and Radio Frequency (RF) capabilities are different, etc., the UE Capability reporting may take up a lot of space. For example, a 5G air interface capability report of a UE may reach the maximum value of 1G byte.

In addition, the new wireless (New Radio, NR) system has measurement configuration information related to Channel State Information Reference Signal (CSI-RS) and random access channel (Random Access Channel, RACH) configuration information. When too many resources are used in the CSI-RS, the corresponding RRC message is too large.

The processing mechanism of the RRC layer entity in the related technology is that the generated RRC message is directly used as the RRC protocol data unit (PDU), that is, the Packet Data Convergence Protocol (PDCP) service data unit (Service Data Unit (SDU) is sent to the PDCP layer entity. The maximum value of the PDCP SDU size is, for example, 8188 bytes in a 4G system and 9000 bytes in a 5G system.

In this way, when the RRC message is too large, it will exceed the limits of the PDCP and SDU and cause excessive demand for the RRC buffer, which will affect the smooth progress of the corresponding communication process.

detailed description

First of all, in order to solve the problems in the related art that when the RRC message is too large, it will exceed the limit of the PDCP and SDU and cause the demand for the RRC buffer to be too large. This embodiment of the present disclosure introduces the RRC segmentation function. The RRC segmentation Functions can be carried by RRC layer entities or by new protocol layer entities. With the introduction of the RRC segmentation function, an excessively large RRC message can be segmented to obtain multiple RRC segmented entities. The multiple RRC segmented entities can carry all the data content in the corresponding RRC message. Each RRC segment entity in the RRC segment entity can carry part of the data content in the corresponding RRC message, and each RRC segment entity is delivered as a PDCP SDU to the PDCP layer entity, so that when the RRC message is too large, it can Adapt to PDCP and SDU, reduce the need for RRC buffers, complete the transmission of RRC messages, and ensure that the corresponding communication process proceeds smoothly.

In specific implementation, after the RRC message is generated by the sender of the communication device (may be referred to as the sender), the corresponding transmission process can be: from the sender's RRC layer entity, the sender's PDCP layer entity, and the sender's radio link control (Radio Link Control (RLC) layer entity, sender Medium Access Control (MAC) layer entity, sender physical (PHY) layer entity, receiver (ie, communication device receiver) PHY layer entity, receiver MAC Layer entity, receiver RLC layer entity, receiver PDCP layer entity to receiver RRC layer entity. In this way, the RRC segment entity generated by the RRC segment function can exist in the form of RRC PDU for the sender, and can be received as PDCP SDU for the receiver, that is, RRC PDU can be equivalent to PDCP SDU.

The data transmission method of the present disclosure will be described below with reference to the embodiments and the accompanying drawings.

Referring to FIG. 1, an embodiment of the present disclosure provides a data transmission method applied to a sender of a communication device. The sender of the communication device may be any one of a terminal and a network device. The method includes the following steps:

Step 101: Generate multiple RRC segment entities.

For the sender, the RRC segment entity may exist in the form of an RRC PDU. Each RRC segment entity in the multiple RRC segment entities carries part of the data content in an RRC message generated by the sender of the communication device, and all data content in the RRC message is carried by the multiple RRC segment entities. The foregoing generation of multiple RRC segment entities can be understood as using the RRC segment entity of the communication device sender or the RRC segment entity of the new protocol layer entity to segment the generated RRC message to obtain multiple RRC segment entities. That is, the RRC segmentation function can be used to divide the generated RRC message into multiple RRC messages for transmission.

Understandably, in specific implementation, corresponding to the uplink data transmission process, the sender of the communication device is a terminal, and the receiver of the communication device is a network device. Corresponding to the downlink data transmission process, the sender of the communication device is a network device, and the communication device receives Fang is the terminal.

For example, if the sender of the communication device is UE1, and an RRC message generated by UE1 occupies 15,000 bytes (exceeding the PDCP SDU limit), UE1 can use the RRC segmentation function of the RRC layer entity (or the new protocol layer entity) to divide the RRC message. Segment processing is RRC PDU1 (such as occupying 7000byte) and RRC PDU2 (such as occupying 8000byte), or segment processing is RRC PDU1 (such as occupying 4000byte), RRC PDU2 (such as occupying 4000byte), and RRC PDU3 (such as occupying 6000byte), as appropriate. Configure PDCP and SDU to complete the transmission of RRC messages.

It should be noted that the above embodiments only take the segment processing as two or three segments as an example, and the specific implementation may also be segment processing into four segments, etc. The embodiments of the present disclosure do not limit this. As for how to process the RRC message in segments, that is, how to select the bytes occupied by the RRC segment entity, the sender can choose as needed, or it can choose based on preset rules.

Step 102: Send multiple RRC segment entities to the receiver of the communication device.

In this way, after the receiver of the communication device receives the multiple RRC segment entities, the multiple RRC segment entities can be reorganized to obtain a complete RRC message.

In the data transmission method of the embodiment of the present disclosure, by generating a plurality of RRC segment entities, each of the plurality of RRC segment entities carries a part of data content in an RRC message generated by a sender of a communication device. All data content in the RRC message is carried by the multiple RRC segment entities. Sending the multiple RRC segment entities to the receiver of the communication device can segment the RRC message, so that when the RRC message is too large, it can Adapt to PDCP and SDU, reduce the need for RRC buffers, complete the transmission of RRC messages, and ensure that the corresponding communication process proceeds smoothly.

In a specific embodiment of the present disclosure, optionally, the grouping information of the RRC segmented entity may include reorganization indication information, and the reorganization indication information is used by a communication device receiver to reorganize multiple received RRC segmented entities. Get the complete RRC message. The above packet information may be a packet header or other forms of cells.

In this way, with the reorganization instruction information, the receiver of the communication device can reorganize the multiple RRC segment entities received, and complete the reorganization of the corresponding RRC messages.

Further, the reorganization instruction information may include at least one of the following:

Segmentation information (SI), sequence number (SN), offset flag value (segmentation offset, SO), and priority indication information.

Optionally, the segment information may be used to indicate the position of the corresponding RRC segment entity in the RRC message, that is, the position of part of the data content of the RRC message carried by the corresponding RRC segment entity in the entire data content of the RRC message. In this way, the receiver can determine the position of the RRC segment entity in the corresponding RRC message according to the segment information, thereby completing the reorganization of the corresponding RRC message.

For example, in specific implementation, the segment information may include X bits, and a typical value of X may be 2. The segment information may be used to indicate the first and middle segments of the corresponding RRC segment entity in the RRC message. (middle) or the last paragraph (last); and other forms of Xbit field meaning can be different from this. In addition, in the case of no segmentation processing, the segmentation information may also indicate that the RRC message corresponding to the corresponding RRC PDU is not segmented.

Optionally, the sequence number may be used to indicate a sequence number of an RRC message corresponding to a corresponding RRC segment entity. In this way, the receiver can determine the RRC segment entity from the same RRC message according to the sequence number, thereby completing the reorganization of the RRC message.

It is worth noting that when the RRC multiplexing function is enabled, the reorganization indication information should include a sequence number so that the receiver can identify the RRC segment entity from the same RRC message. For example, in specific implementation, the serial number may include Y bit, and the typical value of Y may be 1 or 2.

Optionally, the offset marker value may be used to indicate the offset position of the corresponding RRC segment entity in the RRC message, that is, part of the data content of the RRC message carried by the corresponding RRC segment entity is in the entire data content of the RRC message. The offset position. It is worth noting that when the PDCP is delivered out of order, the reorganization indication information should include an offset tag value in order to distinguish the positions of RRC segment entities with similar positions in the RRC message. For example, in specific implementation, the offset marker value may include P bit, and the typical value of P may be 2 or 3. The offset flag value may also be in the form of a segment number, and the present disclosure does not limit the specific form of the offset. If segment numbering is used, Z bits can be used.

For example, if an RRC message generated by a UE is segmented into RRC PDU1, RRC PDU2, RRC PDU3, and RRC PDU4, according to the respective SI, RRC PDU1 is first indicated in the RRC message, RRC PDU2 is the middle and RRC in the RRC message. The middle of PDU3 in the RRC message and the last of RRC PDU4 in the RRC message. At this time, after receiving RRC PDU2 and RRC PDU3, the receiver cannot distinguish between the positions of RRC PDU2 and RRC PDU3 (only knowing that they are in the RRC message According to the offset position indicated by the SO, the RRC PDU2 and RRC PDU3 positions can be distinguished, that is, the RRC PDU2 is located before the RRC PDU3, thereby completing the reorganization of the RRC message.

Optionally, the priority indication information may be used to indicate the reorganization priority of the RRC message corresponding to the corresponding RRC segment entity, so as to complete the reorganization of the RRC message according to the priority level. For example, if there are multiple RRC messages that need to be reorganized, according to the priority indication information included in the RRC segment entity corresponding to each RRC message, the multiple RRC messages are reorganized according to the priority level.

In a specific embodiment of the present disclosure, the packet information of the RRC segmented entity may further include a reserved bit (R bit), and the reserved bit may be used when a new function is subsequently added. In order to ensure that the packet information occupies an integer number of bytes (byte aligned), reserved bits can be filled at positions less than byte.

In the following, some specific uplink-downlink combination configurations in specific implementations are described.

For example, if the uplink and downlink PDCPs are submitted in order and the downlink RRC multiplexing function is enabled, the packet information of the uplink RRC segmented entity may include SI and Rbit, and the packet information of the downlink RRC segmented entity may include SI and SN. And R bit.

For another example, if the uplink and downlink PDCP are delivered out of order, the packet information of the uplink RRC segment entity may include SI, Rbit, and SO, and the packet information of the downlink RRC segment entity may include SI, SN, Rbit, and SO.

For another example, if the uplink and downlink PDCP are delivered in order, the uplink and downlink RRC multiplexing functions are not enabled and no more than one RRC message is sent at the same time, the packet information of the uplink RRC segment entity may include SI and R bit, and the downlink RRC The packet information of the segmented entity may include SI and R bit.

For another example, if the uplink and downlink PDCP are delivered out of order, and the uplink and downlink RRC multiplexing functions are not enabled, the packet information of the uplink RRC segment entity may include Rbit and SO, and the packet information of the downlink RRC segment entity Can include R bit and SO.

In a specific embodiment of the present disclosure, optionally, the foregoing step 101 may include:

Generate RRC messages;

Performing segment processing on the RRC message to obtain the plurality of RRC segment entities.

Among them, the segmentation processing of RRC messages can be implemented by using the RRC segmentation function of the RRC layer entity or the new protocol layer entity.

Optionally, when multiple RRC messages need to be processed in segments, the multiple RRC messages may be processed in segments according to the preset priorities of the multiple RRC messages. For example, in specific implementation, rules such as SRB0, SRB1, and SRB2 can be set in advance over SRB3 and SRB4.

In this way, the RRC messages can be segmented as required, that is, important RRC messages are processed preferentially, and the communication process can be performed smoothly.

Referring to FIG. 2, an embodiment of the present disclosure provides a data transmission method applied to a receiver of a communication device. The receiver of the communication device may be any one of a terminal and a network device. The method includes the following steps:

Step 201: Receive multiple RRC segment entities from a communication device sender; each RRC segment entity in the multiple RRC segment entities carries a part of data content in an RRC message generated by the communication device sender, All data content in the RRC message is carried by the multiple RRC segment entities.

Among them, for the receiver, the RRC segment entity can be received as a PDCP SDU.
